+Subject: [PATCH 3783/4256] drm/amdgpu: Fix KFD-related kernel oops on Hawaii
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Hawaii needs to flush caches explicitly, submitting an IB in a user
+VMID from kernel mode. There is no s_fence in this case.
+
+Fixes: eb3961a57424 ("drm/amdgpu: remove fence context from the job")
